At least on iOS 5, I get very, very good battery life with the iPad (2 and 3). It'll be at 10% battery life and I'd still be able to read on it for over an hour at minimum brightness (auto-brightness off). The iPhone 4S battery doesn't last as long as the iPhone 4 but it still outlasts my Samsung and LG Android smartphones (and that's already with cellular data disabled on Android). The only current iOS device I have with really poor battery life is the iPod Touch (4th gen).
Just updated the iPads to iOS6. So far so good but haven't really played around with it that much. Haven't updated the iPhones (on iOS 5.1.1) or the iPod Touch (on iOS 4.3.5).
